SPECIFICATION forming part of vLetters :Patent No. 707,913, dated August26, 1902.

Application liled April 12, 1902. Serial No. 102,552. (No model.)

To @ZZ whom, it Nif/,ty concern:

Be it known that I, GEORGE HENRY GARRI- sON, a citizen of the UnitedStates, and a resident of Bucoda, in the countyof Thurston and' State ofVashington, have invented a new and Improved Gun-Cleaner, of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in devices for cleaning theinterior of gun-barrels, the object being to provide a simple means forexpanding the swab while operating in a gun-barrel.

I will describeagun-cleanerembodying my invention and then point out thenovel features in the appended claims. n

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters ol reference indicatecorresponding parts in all the figures.

Figure 1 is a` side elevation, partly in section, of a gun-cleanerembodying my invention. Figs. 2 and 3 are sectional details showingdifferent positions of the swab. Fig. 4: is a section showingamodiiication. Fig. 5 is a section on theline am of Fig. 2, and Fig. 6 isa section showing another modification.

The cleaner comprises a tubular handle, preferably consisting ofsections 5 6, having screw-thread engagement one with `the other.Movable in the rod lor handle 5 6 isa pushrod consistingof two sections7` 8, which at the lower end is engaged by an operating-lever 9. Movableon the end of the rod isa sleeve 10, which has connected to it a pin 11,the said pin extending through opposite slots 12 in the rod. Extendedfrom the end of the rod-section 8 and through an opening in a disk 13,mounted loosely on the end of the sleeve 10, is a core 11h-which isverlnicularin form. Mounted on this core is the swab, consisting of aseries of disks 15, formed of metal fabric. The core 11i also extendsthrough an opening in a disk 16 on the outer end of the swab, andbetween the said disk 16 and the head 17 on the coreis a coiledspring18.171? The core 14, especially the portion thereof within the swab, ismade resilient, so as to slightly yield or expand during the movementsof the swab througha gun -barrel, permitting the swab to passobstructions-such, for instance, as lead or hard burned powder.

ln the operation of this device when the swab is inserted the lever 9 isto be operated, so that the inner rod will force the sleeve 10 outward,consequently compressing the swab material longitudinally of the core.By this compression and owing to the shape of the core the swab will becircumferentially expanded by moving the component parts out ofalinement, as indicated in Fig. 3.

1n Fig. 4l have shown the vermicular core 19 as provided at one end withathread 2O to receive the interior thread of a sleeve 2l. On the end ofthis sleeve is a disk 22, having an opening through which the corepasses, and on this disk one end of the swab 23 rests, the other end of`the swab engaging with a disk 24, having an opening through which thecore passes, and between this disk 24 and the head 25 on the end ofthecore is a spring 2 A cord 27 is connected to an eye 2S on the end ofthe core, and connected to an eye on the end of the sleeve 21 is anothercord 29. By means of these cords the swab may be drawn back and forththrough a gun-barrel, and, obviously, the swab may be adjusted to thebore ofthe gun. by turning the sleeve 21, which compresses the swabmaterial, on the core. This core also will be` made resilient for thepurpose before described..

In Fig. 6 I have shown a device somewhat similar to that of Fig. 4; butthe core 30 is flat and sleeves 31 are engaged with each end of it. Bydrawing tightly on the two cords the core will be extended and thediameter of the swab will be reduced.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- 1. In a gun-cleaner, a swab, and a resilientvermicular core extended lengthwise through the swab, substantially asspecified.

2. 1n a gun-cleaner, a swab, a vermicular core on which the swab ismounted, and means for moving the swab lengthwise of the core, wherebythe swab may be caused to take the form of the core to increase itsdiameter, substantially as specified.

3. 1n a gun-cleaner, a swab formed of a plurality oi' disks, avermicular spring-yielding core in the swab, and means for moving theswab lengthwise of the core, whereby the.

IOO

disks may be thrown out of alinement to increase the diameter of theswab, substantially as specified.

4. In a gun-cleaner, a swab consisting of disks formed of metal fabric,a vermicular core extended through the swab, a disk on the end of theswab having an opening, the core being extended through the opening, aspring arranged between said disk and a head on the end of the core, andmeans at the opposite end of the swab for moving it on the core to forcethe disks out of alinement, substantially as specified.

5. In a gun-cleaner, a tubular rod, a pushrod movable therein, a sleevemovable on the end of the tubular rod and adapted to be moved b v thepushrod, a perforated disk arranged loosely on the end of the sleeve, aVermicular core extended through the perforation of the disk, a swabmaterial on said core, a perforated disk engaging with the outer end ofthe swab and through which the core passes, and a spring arrangedbetween said last-named disk and a head on the end of the core,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE HENRY GARRISON.
